Hi Sascha, I've been working on a driver for the dwc2 otg controller, for both host and device mode. Like you I've started from U-Boot driver and I mixed it with some part from Linux. For instance I've removed the register structs and I've been using the same defines for register bit-fields as in Linux. I would like to share my version of the host driver, as the gadget driver one still requires some cleanup. This series is not to be applied on the driver you proposed. However I am willing to propose a new series that can be applied on the driver you proposed. What do you think?
